John Nock and his aerialist wife, Alexandra, will present the AeroSphere Aerial Balloon Show in which Alexandra will perform acrobatic maneuvers over the festival crowd while floating underneath a giant helium balloon.

She will create an interactive performance in the Chrysler Pacifica Family Fun Center during the July 28 to 30 festival at Solberg Airport, according to a news release.

Hailing from seven generations of an entertainment dynasty, John and Alexandra Nock combine aviation, science and aerial acrobatic artistry to create overhead spectacles.
